Randomized Controlled Trial Comparative StudyIntra-articular levobupivacaine, lornoxicam and morphine analgesia after knee arthroscopy: a randomized, controlled trial.
The aim of this study was to compare the analgesic effects of intra-articular levobupivacaine alone, intra-articular levobupivacaine in combination with lornoxicam, and intra-articular levobupivacaine in combination with lornoxicam and morphine on patients following arthroscopic surgery. ⋯ The combination of levobupivacaine and lornoxicam is superior to levobupivacaine alone and the addition of morphine does not improve VAS scores. It appears that the addition of additional drugs for more effective analgesia has its limits.

Functional results of lower extremity lengthening by motorized intramedullary nails.
The aim of this study was to evaluate the outcome of patients undergoing limb lengthening using motorized intramedullary nails. ⋯ While usual complications related to the external fixators, such as pin-track infections and mobilization difficulties were not encountered, the development of additional complications such as dysfunction of the distraction mechanism should be monitored with the use of motorized intramedullary nails in limb lengthening.

Early correction of malunion of distal radius fractures may be necessary in young, active patients. The aim of this study was to report the advantages and disadvantages of early correction of distal radius malunion. ⋯ Advantages of early corrective osteotomy include anatomic restoration at the original fracture line, a shortened healing period and a decreased need for structural bone grafting. Disadvantages are that the recreation of the original fracture line is technically demanding and patients must be cooperative to achieve a successful outcome.

Minimally invasive plate osteosynthesis (MIPO) in diaphyseal humerus and proximal humerus fractures.
Our aim was to evaluate the results of minimally invasive plate osteosynthesis (MIPO) using locking plates in diaphyseal humerus and proximal humerus fractures. ⋯ MIPO of humerus diaphysis and proximal fractures allows for preservation of blood supply in fracture fragments, owing to less soft tissue and periosteal injury. When the procedure is performed with the lateral double incision, exposure and preservation of the axillary and radial nerves are necessary. Early return of function in the shoulder and elbow joints and favorable healing time are the major advantages of this method in this rare subset of humerus fractures.

Cytotoxicity of local anesthetics to rats' articular cartilage: an experimental study.
The aim of this study was to evaluate the effects of both in vivo and in vitro bupivacaine, levobupivacaine and tramadol on articular cartilage and chondrocytes in experimental rat models. ⋯ Although chondrotoxicity of bupivacaine was less harmful than levobupivacaine and tramadol, these findings suggest that local anesthetics may negatively affect articular cartilage and chondrocytes.
